System Troubles
PRIMARY AMP x FAIL The Primary Amp at address x has failed. Call Technical Services.
PRIMARY AMP
x HARDWARE
FAIL
The Primary Amp at address x has had a hardware failure. Call Technical Services.
PRIMARY AMP
x LIMIT The Audio Circuit of the Primary Amplifier at address x has been overloaded or shorted so the
Audio Signal has been attenuated. Check wiring and source and ensure that there are no
shorts.
PRIMARY AMP
x OVERCURRENT The Primary Amplifier at address x has overloaded and shut down. Check the total Load
calculations fir the DS-AMP and/or DS-BDA and ensure the total values do not exceed 120
watts.
PRIMARY AMP
x TRIP The DS-BDA at DS-BUS address x (1-4) is drawing more current from the power supply than
expected and has been disabled. Refer to the DVC manual for additional troubleshooting.
PRINTER OFF LINE Communication loss with printer. Restore power and/or printer’s online status.
PRINTER PAPER OUT Add paper.
PROGRAM CORRUPTED The database that houses the panel’s programming is co
rrupt. It must be re-downloaded, or all
programming must be cleared and re-entered. Service required.
PROG MODE ACTIVATED A user is currently using the p
anel’s programming menus.
REMOTE DISPLAY
x NO ANSWER The remote display at address x is not responding.
REMOTE DISPLAY
x TROUBLE The remote display at address x is in trouble.
REMOTE MIC TROUBLE The DVC’s remote microphone is in trouble. It is installed and super
vised, but no signal is
coming from it. Investigate and fix.
SELF TEST FAILED Diagnostic test failed. Service required. Ca
ll T
echnical Services.
SOFTWARE MISMATCH One or more LCM or DAA software revisions do not match other LCMs or DAAs, and/or the
network communications module is not net
work version 5.0, or LCD-160 software is
incompatible. Update the software as necessary.
STYLE 4 SHORT
x LOOP x Service required. Call Technical Services.
STYLE 6 POS. LOOP
x There is an open circuit on the positive side of loop x. Style 6 and Style 7 are supervised methods of
communicating with addressable devices. If the control panel detects a trouble (open only), it will
drive both ends of the loop, maintaining communication in an unsupervised method. The latching
trouble will display on the panel as a Style 6 trouble until you correct the condition and press reset.
Style 7 configuration of the SLC requires the use of ISO-X modules.
STYLE 6 NEG. LOOP
x There is an open circuit on the negative side of loop x. Style 6 and Style 7 are supervised methods
of communicating with addressable devices. If the control panel detects a trouble (open only), it will
drive both ends of the loop, maintaining communication in an unsupervised method. The latching
trouble will display on the panel as a Style 6 trouble until you correct the condition and press reset.
Style 7 configuration of the SLC requires the use of ISO-X modules.
STYLE 6 SHORT LOOP
x Style 6 and Style 7 are supervised methods of communicating with addressable devices. If the
control panel detects a trouble (open or short), it will drive both ends of the loop, maintaining
communication in an unsupervised method. The latching trouble will display on the panel as a
Style 6 trouble until you correct the condition and press reset. Style 7 configuration of the SLC
requires the use of ISO-X modules.
SYSTEM INITIALIZATION One or more devices (detectors or modules) can not report activation. This can occur following
system st
ar
tup, when exiting Walk Test, or following a device trouble of No Response.
VESDA TROUBLE A trouble has occurred on a VESDA node. Possible troubles may include: Communication failure on
th
e VESDA detector loop, incompatible VESDA software versions, or VESDA configuration error.
